Power Consumption Optimization in IoT based Wireless Sensor Node Using ESP8266

Abstract

In this paper, we present the design and prototype implementation of a weather monitoring system for a college campus powered by a renewable energy source which is based on solar panel for remote applications. The device is powered with the help of rechargeable battery which is recharged through solar energy. Sensors are connected to the device and device uploads these sensor data on cloud with the help of Wi-Fi and internet connection. The main objective of this research is to power this device on renewable energy and continuous sensor data uploading on cloud. To keep device in running mode on battery and to save power deep sleep function of the device is used which consume very less power, which makes it sufficient to run on solar power for long time.
